"I feel really sad, but I think people expected the verdict to be guilty," Nash told the BBC. "I think it's important for artists to be opinionated and it just seems messed up to me that you do that and then you are shut down.

"I am an opinionated person and I want to challenge the world I live in and challenge the government if I don't agree with them.

"It's just terrible, the way they've been treated throughout the trial. It's disgusting and it says a lot of sad things about this world we live in. It's really messed up and really twisted."

Nash has since vowed to keep fighting for the release of Pussy Riot on Twitter, calling for David Cameron to visit the Russian embassy with her tomorrow to put pressure on politicians.
